Developers, journalists and others are invited to submit a digital tool that fights fake news.
The digital tool should be ready in April with the aim of being implemented before national elections in Brazil. The cash prize must be used to improve the tool.
The winning work will be free to be used by any media outlet and will be featured in the Guide to Intelligent Citizenship, a partnership between Catraca Livre and Microsoft.
The deadline is March 15.
